The Batman and the Bridge Builder

Mark Bloschock is an engineer from Texas, and in the late 1970s he got a job with the Texas Department of Transportation renovating the Congress Avenue Bridge. The bridge was a simple concrete arch bridge that spans Lady Bird Lake in downtown Austin. It needed to be rebuilt with more contemporary beams called “box beams.” The box beams sit below the road’s surface, and they needed to be spaced a certain distance apart. Bloschock and the other engineers decided that the gap should be somewhere between ¾ of an inch and an inch and a half, which didn’t seem like a particularly meaningful decision… until the bats moved in.

A tale of bats and bridges and how the built environment and the natural environment don’t need to be at odds with one another.

Plus, we talk with Simon Doble, CEO of Solar Buddy. Light access (both day and night) is a basic need many people take for granted. SolarBuddy is an Australian charity uniting a global community with a big dream to gift six million solar lights to children living in energy poverty by 2030, to help them to study after dusk and improve their education outcomes.

The Nazi Block

In the heart of Berlin’s Tempelhof-Schöneberg district sits a hulking, crumbling concrete cylinder—an abandoned relic of a Nazi plan to rebuild the city as a grand imperial capital. But this eerie structure isn’t just a forgotten engineering experiment; it’s a lasting monument to one of the Third Reich’s most colossal architectural failures.The Nazi Block Subscribe to SiriusXM Podcasts+ to listen to new episodes of 99% Invisible ad-free and a whole week early.

The Wide Open

The Wide Open

Last week, we delved into story of how the Tennessee Valley Authority, which started out as a public institution, ended up acting like a private for-profit company, and the lawsuit that attempted to finally bring the TVA to its heel. Today, Montana Public Radio’s podcast The Wide Open tells the story of a different lawsuit against the TVA that had even bigger consequences. In the 1970s, the fight to save a tiny fish called the snail darter turned the Endangered Species Act from a minor bit of federal law into the most powerful and controversial piece of environmental legislation of the past 50 years.The Wide Open Subscribe to SiriusXM Podcasts+ to listen to new episodes of 99% Invisible ad-free and a whole week early.
